Utilización de la minicomputadora raspberry pi para la adquisición y evaluación de datos de consumo de energía eléctrica de equipos a 220 voltios

Abstract

The following article describes the performance of our graduation project using the DIY ethics (Do it yourself), Open Source technology, programming languages such as Python, and Linux operative system. To implement this project, we used the Raspberry Pi minicomputer and the Arduino Uno electronic board. These devices are used to analyze the power consumption of any electrical equipment, so we needed to set communication between them. During the acquisition process, data is delivered to a web server on real time, where the power consumption of the electrical device is shown. Further, data is collected and saved in a database management tool. Analysis results of electrical devices such as industrial dryers and washing machines show that power consumption vary between 700 and 4000 watts, while a domestic air conditioner needs between 250 and 2000 watts in an analysis time of 10 minutes for both cases.
